CIGARETTE-MACHINE.

Specification of Letters Patent.

Patented Dec. 14, 1915.

Application filed May 6, 1914. Serial No. 836,596.

To all whom it may concern Be it known that I, LOUIS EDMOND RENFJ ROGIER, a citizen of the Republic of France, residing at Paris, France, have invented certain new and useful Improvements in Gigarette-Machines, of which the following is a specification.

In the United States Patent No. 903,101.

dated November 3, 1908 there is described a machine for making a cigarette which is closed at one end. First the tube is made with one end closed, and thereafter the tube is filled with tobacco by means of a plunger apparatus. With the machine of the present invention a cigarette is produced which is closed at both ends and which can be made cheaply and rapidly.

The accompanying drawings lllustrate a machine embodying the invention.

Figure 1 is a side elevation, partly 1n section, of the complete machine for receiv ng a strip of paper, and the tobacco for forming the tube, filling it and closing both ends of it. Fig. 2 is a sectional longitudinal elevation of a part of Fig. 1 on a larger scale. Fig. 3 is a detail of Fig. 2 at a later stage of the operation. Fig. 4: is a section on the hue l4 of Fig. 2. Fig. 5 isa section on the line 55 of Fig. 3. Fig. 6 is a section on the line 66 of Fig. 1. Fig. 7 is a'view of a part of the mechanism of Fig. 6 at a later stage of the operation and wlth an end stop removed to show the action onthe cigarette. Fig. 8 is a longitudinal section of a cigarette with one end closed and'the tobacco filling introduced. Figs. 9 and 10 are respectively a side elevation and endview of the completed cigarette. Fig. 11 is a detail of Fig. 2 in another position of the mechanlsm. Figs. 12 and 13 are sections through Fig. 2 on the correspondingly numbered lines.

Referring to the embodiment of the invention illustrated, the strip of-paper is folded over the mandrel A and carried forward and crimped by means of a roller B, so that it is in tubular form'when it enters a barrel C. As it emerges fromv the barrel it is carried into a notch of the rotating carrier comprlsing a .pair of plates D and D and a proper length thereof is cut off 'by means of shears E E operated by mechanism not herein illustrated. A portion of the tubular stock is left extending beyond the barrel C, and this is caught by a notched plate F which is swung inward and which then rotates around the axis of the tube so as to twist the end thereof and practically close it. The carrier D D is then advanced one step and the next length of paper tube forced into the next pocket of the carrier and out off, these operations being repeated and producing a succession of tubes in the successive pockets of the carrier D, all closed at their forward ends.

The carrier D D revolves step by step in the direction of the arrow in Fig. 6. W hen a tube in one of the notches of the carrier arrives at the lowest point it falls into a notch of a second cylindrical carrier G consisting of a solid drum lying between the planes of the two disks D D and rotating intermittently in a direction opposite to that of the disks D D. The notches in the drum G in succession engage the lowest cigarette tubes in the carrier D D and carry them around to the right, as shown in Fig. 6. The rear, open ends of the tubes are engaged by an inclined guide H (Fig. 1) so as to shift the tubes longitudinally to the desired position. When, in the rotation of the drum, a tube arrives at a point in line with an abutment rod J the latter is pushed forward to press the end of the tube over a funnel K leading from a supply box L which carries a supply of tobacco. lVhile the tube is held in this position, as in Fig. 2, a supply of tobacco is forced into it by the advance of a rod M, and the tube is consequently filled with tobacco. At the end of the operation the rod J is retracted and the rod M advanced sufiiciently to push the cigarette tube back to approximately the point at which it started in its longitudinal movement.

On the second forward step of the drum G, after the filling of the tube, this tube comes opposite a rod N fastened in an arm 0 carried by the reciprocating rod J, so that the filled tube is engaged by the rod N and pushed forward slightly, the rod N thereafter serving as an abutment to receive the endwise pressure against the tube while the open end of it is being closed. lVhen; the rod N has shifted the filled tube to the desired position lengthwise a gripping or clamping means is pressed against the side of the filled tube to prevent it from bending or bulging. This'gripper comprises a strip P (Figs. 6. and 7) of rubber with a hollow face adapted to bear against the side of the tube and carried at the lower end of an arm Q, which is pivoted at its other end to a stationary support and which carries at its lower end a laterally projecting pin R bearing against an arm S which is mounted 011 a shaft T and has a lower arm U bearing on a cam V on a constantly rotating shaft below the body of the machine. The cam alternately presses the arm S outward. which by its engagement with the pin It presses the gripper P away from-the filled tube; or releases the gripper and allows the latter to swing inward with its weight against the side of the filled tube. \Vith the parts in this position, the filled tube supported at its side and its rear end, a bending or crimping means is brought into engagement with its open end so as to close the latter. A pair of pincers X and Y are provided with V-shaped adj acent edges so as to leave an opening somewhat larger than the tube when the pincers are separated, as in Fig. 4;, and with notches Z which overlap each other and leave a slight opening for the paper to project through when the pincers are brought together as in Fig. 5. Each of the pincers is carried by a small lever a pivoted at b and carrying a roller 0 resting upon a cone (Z and held against the same by means of a spring 6. A

key f constitutes an extension of the supporting frame 9 upon which the levers are pivoted, and extends in a key-way through the cone (Z so as to rotate the cone and the levers together but to permit relative movement in longitudinal direction. The cone is mounted on a rod 72, mounted in a hollow support j, the rod being rotated continuously by a pinion is carried on its rear end (Fig. 2) which engages a gear Z (Fig. 1) which is constantly driven through a sprocket m and connections therefrom to the main shaft. The base of the cone is engaged by a fork n. The fork n is mounted on a rod 0 which at its rear end is connected by a link 79 (Figs. 2 and 12) to an arm 9 pivoted on a shaft 7' and carrying a lower arm a at the end of which is a roller engaging in a groove 2? of a cam which is mounted on the continuously rotating shaft TV. The action of the cam groove t is to reciprocate the rod 0, fork n and cone (Z, and thus to bring the pincers X and Y together to bend the projecting end of the tube inward so as to close the same.

In order to hold the closure the paper is twisted after it is bent inward by rotating the pincers and the cone. This rotation is effected by turning the rod it through the gear is as previously described. This rotation is continuous so that the twisting of the end takes place at the same time with the bending inward by the pincers. The notch Z in the working face of each of the pincers permits the portion of the paper at the center to project through the pincers and gives the latter a grip on the paper so as to effectively twist the latter.

The rotating rod h is hollow and carries a central rod '24 which is mounted at its end i on an arm "1) of a rod 10, which is guided in a tubular support in and is connected at its rear end to an upper arm 1 (Figs. '2 and 12) of a hub pivoted at z and carrying a lower arm 10 which has a roller working in a cam 7 groove 11 of a cam mounted on the rotating shaft W. The cam groove 11 is shaped so that just before the cam groove t acts to pinch the end of the tube the rod u is ad vanced into the tube to force the tobacco back from the end and to hold it backuntil the pincers commence to operate; the cam groove 11 being shaped so as to withdraw the rod u as the pincers are brought together by the cam groove t. In the withdrawn position of the rod it its forward end is only slightly in the rear of the pincers so that it abuts against the portion of the paper which extends through the pincers and thus aids in making a perfect closure. in fact by comparison of the cam grooves 11 and t it will be observed that the withdrawal of the rod u and the coming together of the pincers are simultaneous movements. The rod, while the pincers are closing, lies very close to the back of these pincers and is only completely withdrawn therefrom when the action of the pincers is nearly completed. Fig. 11 indicates an intermediate position of the rod u in serving to spread or to hold out the edge of the paper while the pincers 0e and y are bending it inward.

Though I have described with great particularity of detail certain specific apparatus embodying the invention, yet it is not to be understood therefrom that the invention is restricted to the particular embodiment disclosed, as modifications thereof in detail and in the arrangement of the parts may be made by those skilled in the art without departing from the invention.

I claim as my invention 1. Means for closing an end of a cigarette tube containing afilling of tobacco comprising a closing device and a rod adapt- 115 ed to enter the end of the tube and hold the tobacco therein until the closing device commences to operate.

2. Means for closing an end of a 'ciga rette tube containing a filling of tobacco 120 comprising a closing device and a rod adapt ed to enter the end of the tube and hold the tobacco therein until the closing device commences to operate, and means for thereupon withdrawing said rod to a position where it 125 serives as an abutment to flatten the closed en 3. Means for closing an end of a cigarette tube containing a filling of tobacco, which consists of pincers having V-shaped 1 0 faces adapted to be moved toward and away from each other to pinch or to release the end of the paper, and bend the same inward, and adapted in their innermost positions to permit the paper to project through them at the center, and means for rotating said pincers to twist the paper.

4. Means for closing an end of a cigarette tube containing a filling of tobacco, which consists of pincers X and Y having V-shaped faces with central notches Z, means for moving them toward and away from each other to pinch the end of the paper and bend it inward or to release it, the inward movement being limited to permit the paper to project through said notches at the center in the innermost position of the pincers, and means for rotating said pincers to twist the paper.

5. Means for closing an end of a cigarette tube containing a filling of tobacco, which consists of pincers having V-shaped faces adapted to be moved toward and away from each other to pinch or to release the end of the paper and bend the same inward, and adapted in their innermost positions to permit the paper to project through them at the center, and means for rotating said pincers to twist the paper, and a rod adapted to enter the end of the tube when the pincers are separated and to be Withdrawn therefrom as the pincers are brought together.

6. Means for closing the end of a cigarette tube containing a filling of tobacco comprising in combination pincers adapted to bend the end of the paper inward, and an abutment adapted to lie within the end of the paper during the beginning of the inward movement of the pincers.

In witness whereof, I have hereunto siglned my name in the presence of two su scribing witnesses.
